I have a B17a Gsr and i'm having poor gas mileage. When i accelerate it begins to pause at about 3200 RPM or so and doesn't seem powerful for a Vtec. Just bought the car recently and i don't think the last owner gave enough TLC . Anyone have any suggestions on my motor problem?

 

compression/leakdown test and report back.

 

ill most likely run a compression n leak down sometime this weekend. til then any other possibilities why this is happening?

 

maybe it's cat or o2 sensors. go get a diagnostic

 

check obd codes on ecu...its prolly 02s like munkeeboy said also try changin plugs wires and give it some fresh blood

 

Yea, a tuneup might just do the trick, but a bad cat can also make your car hesitate like that. My 00 prelude had a bad cat and it would struggle at low rpm's, around 3 k... and I would have to punch it for it to move...

 

thanks guys. yeah it might be a bad cat due to my muffler hangin off and rattles real bad under the car. i'll let you guys know. thanks for the help

 

A valve adjustment is also most likely needed.
